System structure

A configuration example of a system 1 according to an embodiment of the present disclosure will be described with reference to fig. 1. Referring to fig. 1, a system 1 includes a base station 100 and a User Equipment (UE) 200.

For example, system 1 is a system compliant with 3GPP technical Specification (Technical Specification:TS). More specifically, for example, the system 1 is a system conforming to 5G or NR (New Radio) TS. Alternatively, the system 1 may be a system of TS compliant with LTE (Long Term Evolution: long term evolution), LTE-A (LTE Advanced) or 4G (4 th generation: 4th generation). Of course, the system 1 is not limited to this example.

(1) Base station 100

The base station 100 is a node of a radio access network (Radio Access Network: RAN) and communicates with UEs (e.g., UE 200) located within the coverage area 10 of the base station 100.

For example, the base station 100 communicates with a UE (e.g., UE 200) using a protocol stack of the RAN. For example, the protocol stack includes an RRC (Radio Resource Control: radio resource control) layer, an SDAP (Service Data Adaptation Protocol: service data adaptation protocol) layer, a PDCP (Packet Data Convergence Protocol: packet data convergence protocol) layer, an RLC (Radio Link Control: radio link control) layer, a MAC (Medium Access Control: media access control) layer, and a Physical (PHY) layer. Alternatively, the protocol stack may not include all of these layers, but rather include a portion of these layers.

For example, the base station 100 is a gNB. The gNB is a node that provides NR user plane and control plane protocol termination for the UE (NR user plane and control plane protocol terminations towards the UE) and is connected to the 5GC (5G Core Network:5G core network) via an NG interface. The base station 100 may be an en-gNB. Alternatively, the base station 100 may be an eNB or a ng-eNB.

The base station 100 may comprise a plurality of nodes. The plurality of nodes may include a first node that hosts (host) a higher layer (higher layer) included in the protocol stack, and a second node that hosts a lower layer (lower layer) included in the protocol stack. The upper layer may include an RRC layer, an SDAP layer, and a PDCP layer, and the lower layer may include an RLC layer, a MAC layer, and a PHY layer. The first node may be a CU (central Unit), and the second node may be a DU (Distributed Unit). Note that the plurality of nodes may further include a third node that performs a lower-level process of the PHY layer, and the second node may perform an upper-level process of the PHY layer. The third node may be an RU (Radio Unit).

Alternatively, the base station 100 may be one of the above-described plurality of nodes, and may be connected to other units of the above-described plurality of nodes.

The base station 100 may be an IAB (Integrated Access and Backhaul: integrated access and backhaul) host (donor) or an IAB node.

(2)UE 200

The UE 200 communicates with a base station. For example, when the UE 200 is located within the coverage area 10 of the base station 100, the UE 200 communicates with the base station 100.

For example, UE 200 communicates with a base station (e.g., base station 100) using the protocol stack described above.

In particular, the UE 200 may carry two or more SIM cards. That is, the UE 200 is a multi-SIM UE or a multi-SIM device. The UE 200 is capable of communicating in two or more mobile networks corresponding to the two or more SIM cards, respectively, described above.

For example, the UE 200 can communicate in a mobile network (hereinafter referred to as a "first mobile network") including the base station 100 corresponding to one of the two or more SIM cards described above. Also, the UE 200 can communicate in other mobile networks (hereinafter referred to as "second mobile networks") corresponding to another one of the two or more SIM cards. The first mobile network is different from the second mobile network.

Referring to the example of fig. 2, for example, the UE 200 is capable of communicating in a first mobile network including the base station 100 and a second mobile network including the base station 40. For example, the UE 200 may be in an RRC CONNECTED (rrc_connected) state in the first mobile network and in an RRC IDLE (rrc_idle) state or an RRC INACTIVE (rrc_inactive) state in the second mobile network. In this case, in the first mobile network, when the UE 200 is connected to the base station 100, in the second mobile network, a paging message that the UE 200 should receive may be transmitted through the base station 40.

First embodiment

Referring to fig. 7 to 10, a first embodiment of the present disclosure is explained.

<4.1. Operation example >

An example of the operation of the base station 100 and the UE 200 according to the first embodiment will be described with reference to fig. 7.

The UE 200 (communication processing section 235) communicates with the base station 100 of the first mobile network. For example, the UE 200 is in the RRC connected state in the first mobile network and is connected to the base station 100. On the other hand, the UE 200 is in an RRC idle state or an RRC inactive state in the second mobile network.

The UE 200 (information acquisition section 231) acquires gap-related information about a time gap for the UE 200 to receive paging of the UE 200 in the above-described second mobile network. The UE 200 (communication processing section 235) transmits an RRC message including the above-described gap association information to the base station 100.

The base station 100 (communication processing unit 145) receives the RRC message from the UE 200. The base station 100 (information acquisition unit 141) acquires the gap association information included in the RRC message.

(1) RRC message

In particular, in the first embodiment, the above RRC message is one of the following messages.

RRCSetup complete message

RRCReestablischentcomplete message

RRCResumeCommple (RRC resume complete) message

UE assistance information message

Rrcconnectionsetutpcomplete message

Rrcconnectionreestinglesshmentcomplete message

That is, the gap association information is transmitted in a conventional RRC message.

Thereby, for example, as explained in detail below, enabling the UE 200 to use the time slots for the UE 200 to receive pages in the second mobile network described above. In particular, since the existing RRC message is used to transmit the gap association information, the UE 200 can transmit the gap association information to the base station 100 in the existing process flow. Therefore, an increase in overhead can be reduced. In addition, the complexity of the process flow due to the introduction of a new process flow can be avoided.

(2) Time gap

For example, the time slot includes a paging occasion of the paging in the second mobile network. As an example, the time slot coincides with the paging occasion. With such a time gap, for example, UE 200 can receive the page in the second mobile network without missing it.

For example, as will be described later, the base station 100 (control section 143) determines the above-described time slot.

(3) Gap association information

-request for information

For example, the gap association information includes request information requesting the base station 100 to configure the time gap.

The request information may be information indicating only that the requesting base station 100 configures the time slot. Alternatively, the request information may be information indicating whether the base station 100 is requested to configure the time slot.

Parameter set

For example, the gap-related information includes a parameter set that assists in the configuration of the time gap. Thereby, for example, a more suitable time gap is enabled to be configured.

Specifically, for example, the parameter set includes a paging parameter set for determining a paging frame and a paging occasion of the paging in the second mobile network. Thus, for example, a time slot including the paging occasion of the above-described paging can be configured.

For example, first, the paging parameter set includes configuration information for the paging. Specifically, for example, the configuration information is PCCH-Config or all or part of parameters included in PCCH-Config. The configuration information is included in system information transmitted in the second mobile network. The UE 200 (communication processing section 235) receives the system information in the second mobile network. Then, the UE 200 (information acquisition section 231) acquires the configuration information included in the system information. In addition, the names of the parameters included in the gap-related information may be different from the names of the parameters included in the system information. That is, the parameters included in the system information may be included in the gap-related information by different names.

For example, if the base station 40 of the second mobile network conforms to a TS of 5G/NR, the PCCH-Config includes defaultPagingCycle, nAndPagingFrameOffset, ns, and first PDCCH-MonitoringOccionofPO. default paging cycle is the default paging cycle (paging cycle) used to derive (default) T described later. The nandpnagframeoffset is used to derive the total number of paging frames and the paging frame offset within T described later. ns is the number of paging occasions per paging frame. first PDCCH-MonitoringOccasionofPO indicates (point out) the initial PDCCH (physical downlink control channel: physical downlink control channel) monitoring occasion for paging for each paging occasion of a paging frame.

For example, if the base station 40 of the second mobile network conforms to the TS of 4G/LTE, the PCCH-Config includes a default PagingCycle, and nB. defaultPagingCycle is the default paging cycle that is used to derive T to be described later. nB is used as one of the parameters for deriving paging frames and paging occasions.

For example, the paging parameter set includes an ID of the UE 200 in the second mobile network. For example, in case that the base station 40 of the second mobile network accords with TS of 5G/NR, the ID is 5G-S-TMSI (Temporary Mobile Subscriber Identity: temporary mobile subscriber identity) or the least significant 10 bits of 5G-S-TMSI of the UE 200 in the second mobile network. For example, in case that the base station 40 in the second mobile network accords with the TS of 4G/LTE, the ID is the IMSI (International Mobile Subscriber Identity: international Mobile subscriber identity) of the UE 200 in the second mobile network, or the lowest 10 digits of the IMSI.

Thus, for example, the paging frame and the paging occasion can be determined.

Paging frame (5G/NR case)

In case that the base station 40 of the second mobile network meets the TS of 5G/NR, the paging frame is determined by the following formula.

(SFN+PF_offset)mod T＝(T div N)*(UE_ID mod N)

The SFN is the system frame number (system frame number: SFN) of the paging frame. Pf_offset is an offset for determining the above paging frame. T is the DRX (discontinuous reception: discontinuous reception) cycle of the UE 200. The UE_ID is the least significant 10 bits of the 5G-S-TMSI. N is the total number of paging frames within T.

For example, T is indicated by the defaultPagingCycle included in PCCH-Config. For example, N and PF_offset are indicated by nAcndPagingFrameOffset included in PCCH-Config.

Paging occasion (5G/NR case)

In case that the base station 40 of the second mobile network accords with the TS of 5G/NR, the paging occasion is determined by the following formula.

i_s＝floor(UE_ID/N)mod Ns

i_s indicates the index of the paging occasion described above. The UE_ID is the least significant 10 bits of the 5G-S-TMSI. N is the total number of paging frames within T. T is the DRX cycle of UE 200. Ns is the number of paging occasions for a paging frame.

For example, N is indicated by nAcdPagingFrameOffset included in PCCH-Config. Ns is indicated by Ns included in PCCH-Config.

The paging occasion is associated with the paging frame. For example, the paging occasion starts within the paging frame or after the paging frame.

Paging frame (4G/LTE case)

If the base station 40 of the second mobile network conforms to the TS of 4G/LTE, the paging frame is determined by the following formula.

SFN mod T＝(T div N)*(UE_ID mod N)

The SFN is the SFN of the paging frame described above. T is the DRX cycle of UE 200. N is the smaller of T and nB. nB is the configured parameter. The ue_id is the lowest 10 digits of the IMSI.

For example, T is indicated by the defaultPagingCycle included in PCCH-Config. nB is indicated by nB included in PCCH-Config.

Paging occasion (4G/LTE case)

If the base station 40 of the second mobile network meets the TS of 4G/LTE, the paging occasion is determined by the following formula.

i_s＝floor(UE_ID/N)mod Ns

i_s indicates the index of the paging occasion described above. The ue_id is the lowest 10 digits of the IMSI. N is the smaller of T and nB. T is the DRX cycle of UE 200 and nB is the configured parameter. Ns is the greater of 1 and nB/T.

-request information and parameter set

The gap-related information may include the parameter instead of the request information. In this case, the presence of the above-mentioned parameter set may implicitly request the base station 100 to configure the above-mentioned time slot.

(4) Determination of time gap

For example, the base station 100 (control unit 143) determines the time slot based on the slot related information.

As described above, the time slot coincides with the paging occasion, for example. In this case, the time slot determined by the base station 100 (control unit 143) is the paging occasion determined by the paging parameter set.

(5) Configuration of time slots

For example, the base station 100 (communication processing unit 145) transmits another RRC message including the configuration information of the above-described time slot to the UE 200. The UE 200 (communication processing section 235) receives the other RRC message from the base station 100.

For example, the configuration information includes PCCH-Config included in the gap association information, or includes all or part of parameters included in the PCCH-Config.

For example, the other RRC message is an rrcrecon configuration message or an RRCConnectionReconfiguration message.

Thus, for example, the above time slot is formally shared between the base station 100 and the UE 200.

(6) Paging reception in time slots

For example, the UE 200 (communication processing section 145) monitors the paging in the second mobile network based on the configuration information.

More specifically, for example, the UE 200 (communication processing section 145) monitors the paging in the second mobile network at the paging occasion of the paging in the time slot. For example, when there is a page to the UE 200 at the paging occasion, the UE 200 (communication processing section 145) receives the page. That is, the UE 200 (communication processing section 145) receives the paging message transmitted by the base station 40.

For example, the base station 100 (communication processing unit 145) does not communicate with the UE 200 in the above time slot.

Thus, for example, the UE 200 can monitor for pages in the second mobile network while avoiding interruption of communication in the first mobile network.

(7) Process flow

An example of the processing according to the first embodiment is described with reference to fig. 7.

The UE 200 acquires gap association information about a time gap for the UE 200 to receive paging of the UE 200 in the second mobile network (S310).

The UE 200 transmits an RRC message including the above gap association information to the base station 100 (S320). The base station 100 receives the above RRC message from the UE 200. The RRC message is an RRCSetup complete message, RRCRestagmentcomplete message, RRCRESeConvollecomplete message, UEAssistance information message, RRCConctionSetupComplete message, or RRCConctionReescstagmentcomplete message.

The base station 100 acquires the gap association information included in the RRC message (S330).

The base station 100 determines the time slot based on the slot association information.

The base station 100 transmits other RRC messages including the configuration information of the above-described time slots to the UE 200 (S350). The UE 200 receives the other RRC message from the base station 100. For example, the other RRC message is an rrcrecon configuration message or an RRCConnectionReconfiguration message.

The UE 200 transmits a response message to the other RRC message to the base station 100 (S360). The base station 100 receives the response message. The response message is an RRC message, for example, an rrcrecon configuration complete message or an RRCConnectionReconfigurationComplete message.

The UE 200 monitors the paging in the second mobile network at the paging occasion of the paging in the time slot based on the configuration information (S370). The base station 100 does not communicate with the UE 200 during the above time slots.

<4.2. Variation >

First to sixth modifications according to the first embodiment will be described with reference to fig. 8 to 10. Further, two or more of these modifications may be combined.

(1) First modification example

In the above example of the first embodiment, the paging parameter set for determining the paging frame and paging occasion of the paging includes configuration information (e.g., all or part of parameters included in PCCH-Config or PCCH-Config) for the paging and the ID of the UE 200. However, the above-described paging parameter set related to the first embodiment is not limited to this example.

As a first modification of the first embodiment, the paging parameter set may not include the ID of the UE 200.

First example

The paging parameter set may include configuration information (e.g., all or part of parameters included in PCCH-Config or PCCH-Config) for the paging, an SFN of at least one paging frame of the paging, and an index of a paging occasion of the paging.

The SFN of the at least one paging frame may be a minimum SFN. The index may be the i_s.

Thus, for example, even if there is no ID of the UE 200, the paging frame and the paging occasion of the above-described paging can be determined. Accordingly, privacy problems caused by transmitting the ID of the UE 200 can be solved.

Second example

Alternatively, the paging parameter set may include a period of the paging frame of the paging, an SFN of at least one paging frame of the paging, and an index of a paging timing of the paging.

The period may be T. The SFN of the at least one paging frame may be a minimum SFN. The index may be the i_s.

(2) Second modification example

In the above example of the first embodiment, the base station 100 (control section 143) determines the above time slot. However, the first embodiment is not limited to this example.

Determination of the time gap

As a second modification of the first embodiment, the UE 200 (control unit 233) can determine the above-described time slot.

As described above as an example of the first embodiment, the time slot includes a paging occasion of the paging in the second mobile network. As an example, the time slot coincides with the paging occasion.

The UE 200 (communication processing section 235) may receive the system information in the second mobile network, and the UE 200 (information acquisition section 231) may acquire configuration information (for example, PCCH-Config) for the paging, which is included in the system information. Then, the UE 200 (control section 233) may determine the paging frame and the paging occasion based on the configuration information (e.g., PCCH-Config) for the paging and the ID of the UE 200 in the second mobile network, and determine the time slot.

By such determination of the UE 200, signaling for the configuration of the above-described time slots may be omitted. Thereby, overhead can be reduced.

-gap association information

The gap association information transmitted by the UE 200 to the base station 100 may include a parameter set for determining the time gap. Thus, for example, the base station 100 can know the above-described time slot determined by the UE 200.

The parameter set may include a paging parameter set for determining a paging frame and a paging occasion of a page in the second mobile network. The specific description of the paging parameter set is the same as that in the example of the first embodiment and that in the first modification of the first embodiment. Therefore, duplicate explanation is omitted here.

Arrangement of a time gap

In the second modification of the first embodiment, the base station 100 may not transmit the configuration information of the time slot to the UE 200.

-process flow

An example of the processing according to the second modification of the first embodiment will be described with reference to fig. 8.

The UE 200 determines a time slot for the UE 200 to receive a page to the UE 200 in the second mobile network (S410).

The UE 200 acquires gap correlation information related to the above-described time gap (S420). The gap association information includes a set of parameters for determining the time gap.

The UE 200 transmits an RRC message including the above gap association information to the base station 100 (S430). The base station 100 receives the above RRC message from the UE 200. The RRC message is an RRCSetup complete message, RRCRestagmentcomplete message, RRCRESeConvollecomplete message, UEAssistance information message, RRCConctionSetupComplete message, or RRCConctionReescstagmentcomplete message. Further, the base station 100 (communication processing section 145) may transmit an acknowledgement (confirm) message to the UE 200 in response to the reception of the above RRC message.

The base station 100 acquires the gap association information included in the RRC message (S440).

The UE 200 monitors the paging in the second mobile network for the paging occasion of the paging within the time slot (S450). The base station 100 does not communicate with the UE 200 during the above time slots.

(3) Third modification example

In the above example of the first embodiment, the time slot includes a paging occasion of the paging in the second mobile network, which is determined by the base station 100. As an example, the time slot coincides with the paging occasion. However, the time gap related to the first embodiment is not limited to this example.

-time gap

As a third modification of the first embodiment, the time slot may be a measurement slot (measurement gap) for the UE 200 to receive the page. That is, an existing measurement gap may be used as the above-described time gap.

In this way, by using existing measurement gaps instead of defining new ones, complications in the processing flow in the mobile network can be avoided.

Determination of the time gap

In the third modification of the first embodiment, the base station 100 (the control unit 143) may determine the time slot in the same manner as in the above example of the first embodiment. In particular, in the third modification, the time slot is the measurement slot, and the base station 100 (the control unit 143) can determine the measurement slot.

The base station 100 (control part 143) may determine the paging frame and the paging occasion of the paging based on the paging parameter set included in the gap association information. Then, the base station 100 (control part 143) may determine the measurement gap such that the measurement gap includes a part or all of the paging occasion.

Arrangement of a time gap

As an example of the first embodiment, as described above, the base station 100 (communication processing section 145) transmits other RRC messages including the configuration information of the above-described time slots to the UE 200. The UE 200 (communication processing section 235) receives the other RRC message from the base station 100.

In a third modification of the first embodiment, the time slot may be the measurement slot, and the configuration information may be configuration information of the measurement slot. More specifically, the configuration information may include a measurement gap parameter set for determining the measurement gap.

The above-described measurement gap parameter set may include gapOffset, mgl, mgrp and mgta. mgl is the measurement gap length (measurement gap length) of the measurement gap. MGRP is a measurement gap repetition period (measurement gap repetition period: MGRP) of the measurement gap. mgta is the measurement gap timing advance (measurement gap timing advance). gapOffset is a gap offset that accompanies the gap pattern of MGRP.

Thus, for example, the measurement gap is formally shared between the base station 100 and the UE 200.

Paging reception in time slots

As an example of the first embodiment, as described above, for example, the UE 200 (communication processing section 145) monitors the paging in the second mobile network based on the configuration information.

In the third modification of the first embodiment, the UE 200 (the communication processing section 145) may monitor the paging in the second mobile network at the paging timing of the paging in the measurement gap. In the case where there is a page to the UE 200 at the paging occasion, the UE 200 (communication processing section 145) can receive the page. That is, the UE 200 (communication processing section 145) can receive the paging message transmitted by the base station 40.

For example, the base station 100 (communication processing unit 145) may not communicate with the UE 200 in the measurement gap described above.

Thus, for example, the UE 200 can monitor for pages in the second mobile network while avoiding disruption of communications in the first mobile network.

-process flow

The description of the processing example according to the third modification of the first embodiment is the same as that of the first embodiment described with reference to fig. 7, except that the time gap is the measurement gap. Therefore, duplicate explanation is omitted here.

(4) Fourth modification example

In a second modification of the first embodiment, the time slot includes a paging occasion of the paging in the second mobile network, and is determined by the UE 200. As an example, the time slot coincides with the paging occasion. However, the time gap related to the first embodiment is not limited to this example.

-time gap

As a fourth modification of the first embodiment, the time slot may be a measurement slot for the UE 200 to receive the page. That is, an existing measurement gap may be used as the above-described time gap.

Determination of the time gap

In the fourth modification of the first embodiment, the UE 200 (the control unit 233) may determine the time slot in the same manner as in the second modification of the first embodiment. In particular, in the fourth modification, the time slot may be the measurement slot, and the UE 200 (the control unit 233) may determine the measurement slot.

The UE 200 (communication processing section 235) may receive the system information in the second mobile network, and the UE 200 (information acquisition section 231) may acquire configuration information (for example, PCCH-Config) for the paging, which is included in the system information. Then, the UE 200 (control part 233) may determine the paging frame and the paging occasion based on the configuration information (e.g., PCCH-Config) for the paging and the ID of the UE 200 in the second mobile network. Further, the UE 200 (control unit 233) may determine the measurement gap so that the measurement gap includes a part or all of the paging occasion.

By such determination of the UE 200, signaling for the configuration of the measurement gap described above may be omitted. Thereby, overhead can be reduced.

-gap association information

The gap association information transmitted by the UE 200 to the base station 100 may include a parameter set for determining the time gap. In particular, in the fourth modification of the first embodiment, the time gap is a measurement gap, and thus the gap-related information may include a measurement gap parameter set for determining the measurement gap. Thus, for example, the base station 100 can know the inter-measurement gap determined by the UE 200.

The above-described measurement gap parameter set may include gapOffset, mgl, mgrp and mgta. gapOffset, mgl, mgrp and mgta are described in the same manner as in the third modification of the first embodiment. Therefore, duplicate explanation is omitted here.

Arrangement of a time gap

In the fourth modification of the first embodiment, the base station 100 may not transmit the configuration information of the measurement gap to the UE 200.

-process flow

The description of the processing example according to the fourth modification of the first embodiment is the same as the description of the processing example according to the second modification of the first embodiment described with reference to fig. 8, except that the time gap is the measurement gap. Therefore, duplicate explanation is omitted here.

(5) Fifth modification example

As a fifth modification of the first embodiment, the UE 200 (communication processing section 235) may transmit an RRC message (hereinafter referred to as a "release message") for releasing the above-described time slot to the base station 100. The base station 100 (communication processing unit 145) may receive the release message from the UE 200 and release the time slot.

In a case where the monitoring of the paging in the second mobile network is no longer necessary and the UE 200 ends the monitoring, the UE 200 (the communication processing section 235) may transmit the release message to the base station 100.

After releasing the above time slot, the base station 100 (communication processing unit 145) may communicate with the UE 200 by ignoring the above time slot.

This can shorten the period during which communication is not performed between the UE 200 and the base station 100, for example. That is, a decrease in communication efficiency between the UE 200 and the base station 100 can be reduced.

-releasing information

-positioning of release information

The release message may be an RRC message requesting the base station 100 to release the time slot. In this case, the base station 100 (communication processing section 145) may transmit an RRC message configuring the above-described time slot release to the UE 200 in response to the reception of the above-described release message.

Alternatively, the release message may be an RRC message informing the base station 100 to release the time slot. In this case, the base station 100 (communication processing unit 145) may not transmit an RRC message configuring the above-described time slot release to the UE 200.

-releasing the content of the message

As an example, the release message may include information indicating that the time slot is not required or that the time slot is released.

As another example, the release message may not include the gap association information, thereby implicitly indicating that the time gap or the release time gap is not required.

-specific example of release message

The release message may be an existing RRC message. The release message may be a ueassistance information message, for example.

Alternatively, the release message may be a message defined for the time slot.

-process flow (first example)

A first example of the processing according to the fifth modification of the first embodiment will be described with reference to fig. 9.

The paging to the UE 200 in the second mobile network does not need to be monitored, and the UE 200 terminates the monitoring (S510).

The UE 200 transmits an RRC message (i.e., a release message) for releasing a time slot for the UE 200 to receive the above page to the base station 100 (S520). The base station 100 receives the release message. In particular, in this example, the release message is an RRC message requesting the base station 100 to release the time slot.

The base station 100 transmits an RRC message configuring release of the above time slot to the UE 200 (S530). The UE 200 receives the RRC message. For example, the RRC message is an rrcrecon configuration message or an RRCConnectionReconfiguration message.

The UE 200 transmits a response message to the above RRC message to the base station 100 (S540). The base station 100 receives the response message. The response message is an RRC message, for example, an rrcrecon configuration complete message or an RRCConnectionReconfigurationComplete message.

-process flow (second example)

A second example of the processing according to the fifth modification of the first embodiment will be described with reference to fig. 10.

The paging to the UE 200 in the second mobile network does not need to be monitored, and the UE 200 terminates the monitoring (S610).

The UE 200 transmits an RRC message (i.e., a release message) for releasing a time slot for the UE 200 to receive the above page to the base station 100 (S620). The base station 100 receives the release message. In particular, in this example, the release message is an RRC message informing the base station 100 to release the time slot.

(6) Sixth modification example

In the above examples of the embodiments of the present disclosure, the system 1 is a system conforming to a TS of 5G or NR, or a system conforming to a TS of LTE, LTE-a, or 4G. However, the system 1 according to the first embodiment is not limited to these examples.

As a sixth modification of the first embodiment, the system 1 may be a system compliant with another TS of the 3 GPP. As an example, the system 1 may be a system conforming to the TS of the next generation (e.g., 6G).

Alternatively, the system 1 may be a system conforming to the TS of other standardization bodies related to mobile communication.

In particular, in the second embodiment, the RRC message is an RRC message defined for the time slot. That is, the gap association information is transmitted in a new RRC message defined for the time gap.

Thereby, for example, the UE 200 is enabled to use the time slot for the UE 200 to receive the page in the second mobile network described above. In particular, since the RRC message defined for the above-described time slot is used, the UE 100 can transmit the above-described slot association information to the base station 100 at more flexible timing.

(2) Time gap

The description of the above-described time gap is the same as that in the first embodiment. Therefore, duplicate explanation is omitted here.
